SASHLESS SLIDING WINDOW Filed Aug. 20, 1934 Patented Jan. 14, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to improvements in sliding windows of the sashless type wherein the glass panes are mounted to move sideways for ventilation or other purposes, and the object of the invention is to provide an inexpensive structure which can be easily operated, strong, and present an ornamental appearance.

These objects are attained by the means illustrated in the accompanying drawing, in which:-

Fig. 1 is a perspective view of a portion of a window showing the sills, support and one of the panes and the cooperating means in section;

Fig. 2 is a vertical sectional View on the line 22 of Fig. 1;

Fig. 3 is a horizontal sectional view on the line 33 of Fig. 1; and

Figs. 4, 5, and 6 are detail views hereinafter described.

The framing around and supporting the window and sills is constructed of the usual studs 6-6, and sill beam 1, upon which is mounted the outer-sill 8 and the inner-sill 9 that may be secured in place in any well-known manner.

Preferably, these sills are wooden, and upon the outer-sill is mounted frame-stop I that extends entirely around the window. Rear edge ll of the outer-sill stop is spaced slightly from the front vertical edge l2 of the inner-sill to provide space for the vertical leg I3 of a guide rail extending across the bottom edge of the window and through the space M between the studs 6 to the next nearest studs 6 (one only being shown at one side of Fig. 1) where its bent ends l5 are fastened thereto. This guide-rail is provided with a curved lip l6 which extends its full length and curves downwardly and forwardly from its top edge and with its free edge I1 supported on the top surface of the outer-sill stop Ill.

Studs 6 -6 are spaced sufiiciently apart, not only to permit the guide-rail l3 to pass therethrough, but also to permit the window-panes to slide therethrough when the panes of the window are opened, and each pane I 8 has a shoe l9 secured to its lower edge between the vertical walls of which are mounted ball-bearing sheaves 2!! which are constructed to fit upon the top edges of the guide-rails. The upper edge of each shoe is formed with a longitudinally extending pocket 2| in which the bottom edge of the pane is fitted and secured therein in any suitable manner, rivets, cement or otherwise, and the outer wall of each of the shoes is extended below the plane of the sheaves to slidably engage the curved lip l6 of the guide-rail to form a storm-proof sliding joint, the extensions of the shoes being formed of light flexible metal to permit its adjustment upon the contacting portion of the guide-rail.

The vertical side-stops 22 have their inner edges spaced apart to permit the panes to pass therethrough and said edges are lined with felt 22' to contact and clean the surface of the panes as they slide to and fro.

Panes l8 are preferably arranged in pairs with their vertical meeting edges abutting approximately at the vertical center of the window. The adjacent edges of the panes are provided with rubber or metal contacting meeting strips 23 which are provided with projecting tongues 24, the strip on one pane being positioned opposite to that on the opposite pane, so that, when the panes are in a closed position the fingers form a recess 25 between the rubber strips for the reception of a stop-bumper 26 at the lower edge of the panes. This bumper 26 is removably seated in recesses in the sills 9 and I0 and is located at the parting joint of the guide-rail.

Knobs 2'! are fixed to the adjacent edges of the panes in any suitable manner, and to lock the panes together, a latch hook 28 is pivoted to one of the knobs and formed to engage the opposite knob.

A screen 29 can be fastened across the window at the front, and can be clamped in position between the outer edges of the stops surrounding the window and suitable moulding strips 3il.

It will be understood that the panes will have a sufficient upward play at the top of the window (not shown) to permit the removal of the glass by lifting the panes to clear the guide-rail at the bottom, when the bumper 26 can be removed and the edges of the panes can be slid laterally beyond the center line until the vertical rear edges are withdrawn from the side slots, then the panes can be bodily removed from the frame.

It will thus be seen that the panes are held in equilibrium by the guide-rail and the stops around the window. The front or meeting edges of the panes position the rear edges thereof in the pockets. Hand knobs 21 prevent the panes from sliding too far into the pockets.

The window as described is weather-stripped at all points and operates with silence and ease, and economy is assured by elimination of an expensive frame, thereby permitting the use of a better quality glass for the panes.

What is claimed is:-

1. A sashless window embodying a, pair 1 window-panes, Inner and outer sills, a. guide-rail formed with a vertical wall and a sloping outer wall extending across the bottom of the window, a pair of vertical studs at each side of the window with their inner faces spaced apart to permit the panes to slide therebetween, a metallic shoe secured to the bottom edge of each of the window-panes and having spaced walls, the outer wall being provided with a flexible lip adapted to slide on the sloping outer wall of the guiderail, bearing sheaves mounted between said spaced walls and mounted to roll upon the top edge of said guide-rail, and meeting strips secured to the meeting edges of the window- P211165.

2. A window embodying a pair of Irameless glass panels, a guide-rail extending across the bottom of the window to bodily support said panels in a vertical position, a metallic shoe secured to the bottom-edge of each of the panels and provided with a groove to receive said bottom-edge and also depending vertical walls forming a housing, bearing sheaves mounted in said housing and adapted to roll back and forth on said guide-rail, and a removable bumper stop arranged centrally of the window and adapted when removed to permit the glass panels to slide beyond the central line of the window so that the rear-edges of the panels can be released from the guide-walls and the panels be removed from the frame.
